Tropical Storm Melissa is predicted to escalate to a uncommon category five cyclone as it veers toward Jamaica, causing life-threatening sudden floods and landslides.
This weather system, which had winds of up to 120 mph as of 06:00 GMT, is currently turning northwest in the Caribbean Sea and is expected to make landfall by early next week, based on data from hurricane specialists.
Warnings of blackouts and structural damage have been issued as this storm produces up to thirty inches of precipitation and storm surges as high as thirteen feet above typical tides. "Take cover without delay," locals have been advised.
Melissa is the 13th named hurricane in the current Atlantic hurricane season, which typically ends in late autumn.
A highest-level hurricane is the strongest type, with wind speeds of at least 157 miles per hour.
While Melissa is projected to diminish in strength to a Category 4 hurricane before arriving at Jamaica, experts said there was "minimal real distinction in the overall impacts" upon landfall, and that the cyclone will be "at least that intensity" when it strikes the nation.
With tropical storm-level winds and rain already expected well before it passes over the island's interior - including potentially the city of Kingston - warnings emphasize that "readiness efforts must be accelerated".
"Several days of harmful winds and torrential rain have begun and will cause severe and deadly flash flooding and many landslides," counseled meteorological officials.
The nation's leader Andrew Holness stated: "I know that there are numerous residents who are concerned, who are very concerned, and appropriately: worry is natural.
"Yet the optimal approach to manage nervousness and any unease and worry is to remain prepared."
Locals are being instructed to protect their properties with sandbags and wooden boards, and to accumulate essentials.
Alerts are also ongoing for parts of Haiti including the primary urban center, the adjacent nation and Cuba's eastern region, where the hurricane is anticipated to bring comparable impacts by the middle of next week.
Landslides presently generated by the storm have resulted in two fatalities in the country, according to emergency services.
The hurricane is forecast to cross Cuba by Wednesday before moving through the Caribbean archipelago and entering the Atlantic Ocean.
By the moment it makes contact with the Caribbean nation, it is forecast to have reduced to a third-level hurricane.
Although it is challenging to associate specific storms to environmental shifts, scientists say it is making climate patterns increasingly frequent and more severe.
Higher ocean heat generate greater water vapor in the air, helping fuel the formation of hurricanes.
Ahead of the beginning of this year's Caribbean cyclone season, weather organizations projected above-normal activity, mentioning heated marine conditions and possible stronger monsoon activity around West Africa - where hurricanes frequently develop.
